Why Ξ (Delta)?
Delta (Ξ) symbolizes change, a concept familiar to every robotics team. Whether itβs completely rebuilding a robot from the ground up or making incremental improvements, such as refining an intake system, change is an essential part of the process. By embracing change, we embody the spirit represented by our name, Ξ (Delta).

Code Examples
Inline Code
To initialize a motor, use the motor.spin() function in your code.
The variable driveSpeed should be set between 0 and 100.
Code Block - Python
# VEX V5 Python - Autonomous Routine
def autonomous():
# Initialize motors
left_motor = Motor(Ports.PORT1)
right_motor = Motor(Ports.PORT2)
# Drive forward for 2 seconds
left_motor.spin(FORWARD, 50, PERCENT)
right_motor.spin(FORWARD, 50, PERCENT)
wait(2, SECONDS)
# Stop motors
left_motor.stop()
right_motor.stop()
print("Autonomous completed!")
Code Block - C++
// VEX V5 C++ - Driver Control
void opcontrol() {
while (true) {
// Get joystick values
int forward = Controller1.Axis3.position();
int turn = Controller1.Axis1.position();
// Tank drive control
LeftMotor.spin(vex::forward, forward + turn, vex::percent);
RightMotor.spin(vex::forward, forward - turn, vex::percent);
// Small delay
vex::task::sleep(20);
}
}
Code Block - JavaScript
// Sensor Reading Example
function readSensors() {
const distance = RangeSensor.distance(MM);
const rotation = InertialSensor.rotation(DEGREES);
console.log(`Distance: ${distance}mm`);
console.log(`Rotation: ${rotation}Β°`);
return { distance, rotation };
}

Important Note: Always test your robot in multiple environments before competition day.
Safety Reminder:
- Wear safety glasses when operating power tools
- Keep workspace organized and clean
- Never force mechanical components
